Can't ping Switch from PC (using VLANS)

Hello, I'm using Cisco Packet Tracer and trying to configure VLANs and routing between them. Here are two tables, which I have used for configuring:

Device

Interface

IP address

Subnet mask

Default gateway

My ,pkt file looks like:

Gugolsan_0-1668909082155.png

I have connected and customized devices, customized VLANs and trunks on switches, customized routing between VLAN based on trunk. Then I have been pinging from PC-A to gateway VLAN 10 with address 192.168.10.0, from PC-A to PC-B, from PC-A to Lo0, from PC-F to PC-S and from PC-S to S2. Everything has been succeded except last: ping from PC-S to switch S2. Where can be the problem? Any ideas?

ping from PC-S to SVI VLAN1 in SW1 and SW2, are ping success ??

No, I have used ping 192.168.1.11 and 192.168.1.12. In both cases request timeout.

last commend 
add below command in both SW (SW1 & SW2)


ip default-gateway 192.168.1.1

Done.

 

it ping now ?

 

Unfortunately, not, maybe you can take a look by yourself using my .pkt file? Maybe you will see something missing?

the file is not open ,
one more thing PC-S connect to SW2 port, are the port assign with VLAN 10?

What do you mean not open? Yes, there are allowed VLAN 1,10,20,123 and the port is assign with VLAN 20.

assing with VLAN 20 but some PC like PC-A and PC-S must assing to VLAN 10 

can you copy paste the config of SW and router here ?

I have pasted previously two times, but it has dissappered...
